* gdbarch.sh (software_single_step): Remove "insert_breakpoints_p" and

"sig" arguments, add "regcache" argument.
	* gdbarch.c, gdbarch.h: Regenerate.

	* infrun.c (resume): Update SOFTWARE_SINGLE_STEP call arguments.
	(handle_inferior_event): Call remove_single_step_breakpoints directly
	instead of calling SOFTWARE_SINGLE_STEP to remove breakpoints.

	* alpha-tdep.c (alpha_software_single_step): Update argument list.
	Remove handling of !insert_breakpoints_p case.
	* arm-tdep.c (arm_software_single_step): Likewise.
	* cris-tdep.c (cris_software_single_step): Likewise.
	* mips-tdep.c (mips_software_single_step): Likewise.
	* rs6000-tdep.c (rs6000_software_single_step): Likewise.
	* sparc-tdep.c (sparc_software_single_step): Likewise.
	* spu-tdep.c (spu_software_single_step): Likewise.

	* alpha-tdep.h (alpha_software_single_step): Update prototype.
	* mips-tdep.h (mips_software_single_step): Likewise.
	* rs6000-tdep.h (rs6000_software_single_step): Likewise.
